Blair's Caldera Hot Sauce — 13 Million Scovilles

Only 499 of these 12-inch tall, three-bottle high, monstrosities were ever made. The skull atop the stack of bottled pain is dipped in 24 karat gold. Buying bottles of Caldera second-hand can run you many thousands of dollars. The bottom bottle is around 1.5 million Scovilles, the middle layer cranks the heat up to 5 million Scovilles and the top layer has visible capsaicin crystals floating in oil and rates between 10 million and 13 million Scoville units.
